Assessing whether progesterone-matured dendritic cells are responsible for retention of fertilization products in missed abortion
We hypothesize that progesterone causes tolerogenic maturation of myeloid dendritic cells (DCs) in human decidua of threatened miscarriage or missed abortion characterized by a distinct phenotype and cytokine production, including reduction of the main NK cell proliferation and cytotoxic factor interleukin (IL)-15. During DC/NK cell interaction, progesterone-shaped DCs cannot efficiently multiply or equip NK cells with the cytotoxic mediators peforin and granulysin, which might harm trophoblasts and induce abortion.
